      Thanks. I assume you are referring to my post #1 which was over 2 years ago now. As per post #3, if I wasn't clear, I abandoned O-rings...

      Hi. Subsequent to that post I ended up buying a stick of Teflon (or so they say it is) from AliExpress & machined some washers for both...

      From what I have read on multiple forums, it wouldn't be the first time & likely wouldn't be the last time an IMP leadscrew was packaged...

      This post made me go out & check my own lathe. I engaged thread mode lever, clamped the half nuts so they were fully engaged, moved the...

      How can you be so sure? What if the collar is slowly slipping over time? Maybe the new machine was something acceptable like 0.050"...

      I think I understand what you are saying but maybe where we differ is the implications & numerical extent. Lets say we know for a fact...

      Everything you are talking about assumes that this is a THREAD backlash problem between the lead screw & half nut threads. Yes, if for...

      Now I'm assuming the leadscrew is a solid because that's how it appears in parts view. In the picture it looks like slightly different...

      petertha replied to the thread Little Demon V8 - helpful hints (hopefully).
      Nice work. Just curious about your tool. Is it made from a slitting saw blade or uni-blade with relief or...? Reason I ask is it looks...

      petertha replied to the thread Thread Dial.
      Do you mean it appears the leadscrew can free rotate 1/8" like in a 12:00 to 1:00 manner? If you are saying the carriage can float...
